This invention-relates to an oil filter and particularly to an improvedmeans of fastenin the various fittings to the lter can.

t is the object of the invention to construct s a securin means for thefittings of the filter which render the `fittings readily removable andat 'the same time `form a compact construction, and a reinforcement forthe lter cover.

The object of the yinvention is accomlshed by placing on the inner sideof the lter cover a relatively stili and unyielding member. This memberis referably a casting having a plurality of t readed `openin s, i and acentral opening for the reception of t e connection for securing theltering materialto the cover. A trian lar casting is used, although theshape is immaterial, and steel may be used instead of a casting. Outsidece the cover there is applied the -itting which contains the inlet andoutlet ports as well as a by-pass. The tting has openings arranged' toconform to the openings of the member on the inside of the cover. Boltsare passed through the openings in the ittin and screwedinto the mem erto rigidly ho d the fitting on the filter cover. Gaskets are apliedbetween the fitting and the cover and tween the holt heads and thefitting to form a liquid tight connection. By the application of thereinforcing member on the inside of the cover, the relatively thin metalof the.

cover will conform itself thereto giving a Br good seat for the gasket.A

J The fitting has a passage arranged between the base and the apex of atriangle formed by the bolt holes and a second passage outside thetriangle, both passages being preferably, though not necessarily,parallel to the base of the triangle.

The filtering unit may be secured to the cover either by means of a nutthreaded onto an extension passin through the opening in the reinforcingmem er or by means of a pipe'- ing shown in section for purposes ofclearer,

illustration.

Figure 2 is a bottom plan view of the castin taken on the line 2-2 ofFigure 1.

igure 3 isa plan view on a reduced scale of a structure of Figure 1. re4 is a view-similar toFigure 1 of a Fi modified form ofthe filtersecuring means.

Referring to the number parts on the drawing, 10 indicates a lter canhaving a wall or cover 12. and a bottom 14. Within the can there ispositioned filtering material 16, secured to a stud 18 and heldin laceby means of the screen 17, theupper and lowerstampings 20 and. 22, andthe straps 24. A spring 26 rests on the bottom 14 and presses upwardlyon the lower stamping 22 and assists in maintaining the filteringmaterial in posi-` tion. The arts so far described are conventional andorm no part of the invention.

Positioned on the inside of the cover is a reinforcin member 28 of anysuitable kind but is pre erably in the form of a casting or stampinghaving a plurality of threaded openings shown as three in number, 30, 32and 34, arranged in triangular formation as 1s seen Figure 2, althoughany number of o nings may be used. T e central portion o the casting 28has an opening 36 throu h which is passed the threaded end 38 of t estud 18. The casting is further provided with an passage tioned on theopposite side of the cover Vis a ofening 40 which serves as an outletgasket 42 vhaving openings to conform to the o nmgs of the reinforcingmember 28.

ated on the asket 42 is the fitting 44 rovided with a urality ofopenings 46,`w` ich conform to t e openings in the member 28.

filter with the iss or the oil from the filter. Posi- Passing throughthe openings 46 and thread- Considering the line through the boltsA 50 Aand 5 2 as the base of a triangle it will bel noted that the fitting 44has an inlet passage 54 positioned between the base and apex of thetriangle and arranged parallelto the base. The fitting is furtherprovided with an outlet passage 56 and a passage 57 which is generallyparallel to the base and 52, but which lies wlthout the triangle. Itwill thus be seen that the fitting has one passage 54 between the boltsand a second passage -57 outside thereof.

The fitting is rovided with thejusual byass (not shown? between theinlet and outet ports and with the test valve 58. These parts areconventional and form no part of the invention.

The construction of Figure 4 differs from that of Figure 1 in that adiierent means of securing the ilterin material 16 and its associatedparts to the lter cover 12 is provided. Instead of the threaded portion38 of the stud 18, a pipe 60 is used to form the inlet to the filteringmaterial 16. This pipe is riveted over as shown at 62 in order to orm aclose contact with the cover 12.

In order to remove the fitting from the iilter, all that is necessary isto unscrew bolts- 48 from the threaded openings 30, 32 and 34 in thecasting 28. This will permit the rcmoval of the tting and the separationof the old filter from the reinforcing member and the annexation of anew one.

I claim:

1. In an oil filter, a container, a fitting having a plurality of boltopenin s, a means for securing the iitting to the t'er containercomprising a member placed at the Wall of the container opposite thefitting, and a plurality of bolts passing through said tting and member,said bolts arranged at the apices of a triangle and said fitting havingan oil passage arranged in a plane parallel to one of the sides of thetriangle.

2. In an oil filter, a container, a fitting having a plurality of boltopenin s, a means for securing the iitting to the lter containercomprising a member placed at the wall of the container opposite thefitting, and a plurality of bolts passingthrough said litting andmember, said bolts arranged at the apices of a triangle and said fittinghaving an oil passage outside the triangle.

3. In an oil filter, a container, a triangular plate inside saidcontainer abutting yone of the filter walls, an oil fitting outsidethcontainer and abuttin the other side of thvall bolts arranged at t eapices of a triangl." an

passing through said fitting and wall" and entering said plate to securesaid parts together, an oil passage in said head inside sald triangle,and an o il passage in said head outside said triangle.
